BOTTLE-QLOSURE.

' Patented Aug. 17, 1915.

Application filed September 30, 1911. Serial No. 652,068.

To all whomit may concern:

Be it known that I, MAXIMILLIAN P. JANISCH, a citizen of the United States, residing at. Milwaukee, county of Milwaukee, and State of IVisconsin, have invented new and useful Improvementsin Bottle-Closures, of which the following is a specification.

- My invention relates to improvements 1n bottle closures. I

The object of my invention is toprovlde a bottle closure which will be perfectly sanitary, inexpensive in construction, and capable of being readily applied and easily detached.

The ordinary milk containing bottles are formed with a mouthpiece having an interior shoulder which receives a circular disk or cap of flexible material. But this disk 1s necessarily set into the mouth of the bottle, and dust collects above and upon it. Also the top of the bottle is exposed and both the bottle and the cap frequently become sticky from the escape of a few drops of milk, and infected by contact with the hands of the vender whousually grasps the bottle at its upper end. "Under such conditions, it is almost impossible to remove the cap and pour out the contents without infecting the milk, and a special object of my invention is therefore to provide a form of cap which will completely, cover the upper end of the bottle, providing no lodging place for dust, and protecting allparts of the bottle touched by the milk while contained in it, or while being poured from it, against contamination. X

In the drawings :F,igure 1 is a side elevation of a glass milk bottle and its closure, part in section, embodying my invention. Fig. 2 is a similar view, showing my invention applied to the mouthpiece of a paper bottle. Fig. 3 is-a detail sectional view of a bottle mouthpiece, provided with a cap of ordinary type, with a supplemental cup also applied thereto and embodying my invention.

Like parts are identified. by the same of the bottle. The mouthpiece is provided with an interior shoulder O of ordinarytype, adapted to receive an inset cap. But

I also provide the mouthpiece with an ansions to permit a sheet of suitable covering paper to be folded smoothly over it without :cutting or tearing. A. similar rib F of somewhat larger size, is formed below the groove D. A strip of paper G, coated on its under surface at least, with paraffin or other suitable waterproofing material, is adjusted over the mouthpiece of the bottle, and its margins folded downwardly about said mouthpiece, and held in position by a spring wire split ring H, which engages the paper and binds it in position by pressing into the groove D, as illustrated. The ends of'the ring G are beveled, thus permitting them. to lap upon or past each other if desired, or in case it is applied to a mouthpiece of less than normal size. The strip or piece of paper G may be covered by another piece of paper I, if desired, the latter being applied preparatory to the adjustment of the ring and also clamped in position by the ring.

It will be observed that the piece or pieces of paper G, (or G and I) form a cap for the bottle, which fits smoothly over its top, and not only retains the contents, but protects the entire mouthpiece from contamination and provides no dust retaining pockets above the-mouthpiece. The-ring being of resilient material, and split, it is obvious that it will expand sufliciently to allow it to be forced by machinery over the rib E, 'andthis draws the paper forcibly down over the top of the mouthpiece as the ringmoves to its position v in registry with the groove" D. The lower rib F, being larger, obstructs the downward movement of the ring and holds it in registry with the groove, until it moves to clamping osition therein. If desired the ring may. efirst heated and adjusted in position, while hot enough to melt or partially melt the paraffin against the .base of the channel D, thus hermetically sealing the bottle; will be found, however, that even with heating or melting the paraflin, an air tight closure will be provided.

Referring to ig. 2, it'will be observed It' out to a mouthpiece B similar in form to that s own and described in Letters Patent of the United States, granted to me for a milk receptacle, and in which a non-metallic or wooden mouthpiece is shown as applied to a paper bottle. In either case, it is desirable to retain an interior shoulder as shown at C,

thus permitting the insertion of a disk cap K, (Fig. 3), whereby the contents may be ring substantially filling the groove and binding the cap therein, said ring being 2 adapted to prevent either an upward or downward, slipping movement of the cap with reference to the bottle. A 2. The combination with a bottle having a mouth piece projecting outwardly beyond the. vwall of the bottle immediately above such wall, said outwardly projecting portion being provided with an annulargroove adapted to receive a cap holding wire ring, a flexible impervious covering for the mouth piece, having marginal portions down turned to cover said groove, and a resilient split ring binding said coveringin the groove substantially filling the groove, said J ring having beveled ends abutting each other in said groove, substantially as described.

3. The combinationwith a bottle having v a mouth piece provided with an annular groove adjacent to its upper margin, the portion of said mouth piece below said groove being larger in diameter than the portion above said groove, a flexible cap adapted to cover said mouth piece, and a split ring of resilient material engaged in said groove and substantially filling the same with the' ends of said rings alined and in substantially abutting contact. v 4. A bottle provided near its upper end -with an outwardly projecting annular rib and an inwardly extending annular groove immediately above said rib and in close proximity to the mouth of the bottle, a flexible cap covering said bottleand extending downwardly across said groove, and a split ring substantially filling the groove and binding the cap therein, said ring being adapted to prevent either an upward or downward slipping movement of the cap with reference to the bottle, said cap including an impervious layer connected with the walls of the groove by adhesive material hermetically sealing said bottle.

. In testimony whereof I affix my signature in the presence of two witnesses.
